Country singer and former “American Idol” contestant Kellie Pickler has a whole new challenge ahead of her on “Dancing with the Stars.”

Access Hollywood’s Shaun Robinson caught up with Kellie and her professional partner, Derek Hough, as they rehearsed for their “DWTS” debut.

“What’s been the hardest [thing to do]?” Shaun asked.

“All of the above,” the 26-year-old singer said with a laugh. “I’m working muscles that I didn’t know I had. It’s hard all the way around. I’m definitely stepping outside my comfort zone.”

The ABC show’s often-skimpy outfits might also be a little hard for Kellie to adjust to.

When Shaun inquired about her first outfit, Kellie shyly said, “Whatever covers the areas that need to be [covered].”

She then joked that she would do whatever it takes to get votes, saying, “Well, it’s all about ratings… We’re doing the naked cha-cha!”

As for a country music showdown in the ballroom between Kellie and fellow competitor Wynonna Judd, Kellie stressed that she just wants their shared hometown of Nashville to shine.

“I told her, when we first found out that [we were both] on the show, I said, ‘Hopefully one of us Nashville girls will bring that ball back to Tennessee,’” she recalled. “Hopefully one of us will, that’s our goal.”

Adding, “I love [Wynonna]! She’s country music royalty. It’s an honor to be able to share the stage with her.”
